概述
柏氏似鳞头鳅（Lepidocephalichthys berdmorei）与不少同属鱼不同，偏好清澈流动的源头溪流。它成年较大，体侧斑点大小不一且不成纵带，是选鱼和辨认时值得注意的特点。
分布与栖息地
广布孟加拉国、印度东北部、缅甸、泰国和老挝多个水系，中国记录未得到确认。常在石块、卵石及淹没根系间活动，也会进入积叶沙泥区；季风影响水量、流速和浑浊度。
饲养环境
至少参考 75 × 30 厘米底面积，大小石块、砾石及沉木构成流水环境和阴影。可附生耐流植物，较亮照明能促进附着生物。使用成熟过滤、足够增氧和水流，每周换约 30%～50%；较能耐受一些环境波动不意味着可忽略维护。
食性与喂食
下沉干粮搭配小型活冷冻水蚤、丰年虾、红虫等；天然可能偏捕食小型动物，不应只喂单一干粮。
习性与混养
可与合适大小的温和溪流鱼、耐流鳅或虾虎搭配，避免强占底部地盘的种类。同属群养建议为四尾以上，卵和鱼苗可能被吃。
雌雄区分
雄鱼胸鳍增大，最内侧第七、八鳍条融合增厚成圆柱样结构；雌鱼通常稍大、较厚实。
补充说明
尾鳍可见多条暗带和基部大黑点，近似种的成年大小与雄鱼胸鳍结构不同。眼下棘可挂网，操作时注意。

Overview
Unlike many relatives, Lepidocephalichthys berdmorei favors clear flowing headwaters. Its relatively large adult size and irregular flank blotches, rather than continuous stripes, are useful considerations when choosing and identifying fish.
Distribution & habitat
Its broad range includes Bangladesh, northeastern India, Myanmar, Thailand, and Laos; Chinese records remain unconfirmed. Rocky streams and submerged roots are common habitat, alongside some sandy or muddy leaf-collecting areas. Monsoons change water level, current, and clarity.
Aquarium setup
Use at least a 75 by 30 cm base with stones, gravel, and wood arranged for cover and flow. Hardy attached plants can be included, while good lighting encourages surface growth. Mature filtration, oxygenation, and circulation are important, with weekly changes around 30–50%. Relative tolerance does not remove the need for regular care.
Diet & feeding
Offer varied sinking prepared foods with regular small live or frozen invertebrates. Natural feeding probably emphasizes tiny animal prey, but the aquarium menu should not depend on one dry product.
Behaviour & compatibility
Compatible peaceful stream fishes, selected current-loving loaches, or gobies can work. Avoid aggressive substrate defenders. Genus-level recommendations favor at least four together, while eggs and fry remain potential prey.
Sexual dimorphism
Males develop enlarged pectorals with fused thickened inner rays forming a cylindrical structure. Females are typically larger and fuller-bodied.
Notes
Several dark tail bars and a prominent tail-base spot contribute to identification, alongside adult size and male pectoral structure. Subocular spines require care when netting.
